Does it handle punctuation correctly in Sentence Case?
Yes! Our algorithm looks for periods, exclamation marks, and question marks to determine where a new sentence starts, ensuring the next letter is properly capitalized.
Is there a limit to how much text I can convert?
You can paste entire articles or long lists of data. The conversion happens locally in your browser, so it’s nearly instantaneous regardless of length.
Can I use this for coding (e.g., camelCase or snake_case)?
While this tool focuses on prose, it’s a great starting point. If you need specific programming formats like kebab-case, look for our Developer Case Converter (coming soon!).
